At this point I think unles you are on a flight longer than four hours, I wouldn't count on food service from any carrier. You can always bring on sandwiches from home, eat right before you get on the plane, etc. In all honesty, with winter quickly approaching, and plane that can sit fully loaded on tarmacs for quite some time, I would always suggest bringing something to eat on with you--granola bars, energy bars, etc., just in case.
